SLATE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 562,051, dated June 16,1896.

Application filed September 11, 1895. Serial No. 562,195. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL D. VAN PEL",

a citizen of the United States, and a resident of Anderson, in thecounty of Madison and State of Indiana, have invented certain new anduseful Improvements in Slate-Cutting Machines; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a side elevation of theinvention,showinghandle raised. Fig. 2 is a plan view of same withhandle removed; and Fig. 3. is a sectional view on line 0000, Fig. 1.

The object of this invention is to provide a simple and effectivemachine for cutting and trimming slate; and the invention consists inthe novel construction and combination of parts,all as hereinafterdescribed, and pointed out in the appended claims.

Referring to the accompanying drawings, the letters A A designate twoparallel side pieces or cheeks of the frame, which consist ofvertically-disposed bars supported at one end by a leg 13 and at theopposite end by the two legs C O. The bars constitute the table of themachine.

The upper end of the leg B passes between the two bars, which aresecured thereto by bolts 1). The legs 0 O are connected with said barsby means of bolts 0, which also pass through a spacing-block D, placedbetween the bars to hold them the proper distance apart. Should it bedesired to vary the distance between the bars, additional spacing blocksor washers may be employed. The lower ends of the legs are provided withperforated feet d, and these feet are preferably formed with spurs d, inorder to hold the machine on a roof or other place where it may be used.

E designates the knife blade, which is shaped similarly to a shear-bladeand is pivotally secured between the bars A A at c. Said knife has ahollow or concaved edge, as best shown in Fig. 3, forming the two sharpcutting edges ff, which grasp and hold the slate firmly while it isbeing cut. It will also be observed that the upper edges of the bars A Aare outwardly beveled, as indicated at a a, to better adapt them to theslate, which is often sprung or hollowed. edges are also preferablyconvened longitudinall'y or raised gradually from each end toward thecenter or near the center, which is the highest point. By reason ofthispeculiar formation of the blade and of the table it is possible tocut the slate in a true and neat manner without breaking or chipping.The cutter-blade is preferably thickest at the cutting edge, itsthickness gradually diminishing toward the upper edge.

One of the bars A is provided with slotted arms G G, which support gagesH. Said arms G G are preferably secured to the bar A by means of boltsg, which engage slots g in lugs g of the arms G, whereby the said arms,with the gages, may be readily detached.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1. In a slate cutting and trimmingmachine, the combination with a table composed of two parallel barswhose upper edges are outwardly beveled, of a knife-blade pivotallyattached to said bars and having a hollow or concaved cutting edge,substantially as specified.

2. In a slate cutting and trimming machine, the combination with a tablecomposed of two parallel bars whose upper edges have lateral anddownward bevels and are raised or inclined from each end toward thecenter, of a pivoted knife-blade connected to said bars and having ahollow .or concaved edge, substantially as specified.

3. In a slate cutting and trimming machine, the frame having the legs Band O, O, and the side bars A, A, secured to said legs, of a cutting-barhaving a groove and the two cutting edges, substantially as specified.

4. In a slate cutting and trimming machine, the combination of the tablecomposed of the two edgewise-disposed bars having the inclined upperedges, the legs B and O, C, to which said bars are secured, said legshaving spurred feet, the pivoted cutter-bar having the concaved cut-tingedge, and the gages attached to one of said bars, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL D. VAN PELT.
